RESUMEN
BACKGROUND: Transverse myelitis (TM) is a demyelinating inflammatory disease that presents with motor, sensory, and autonomic dysfunction, which may be acute or subacute. COVID-19-associated TM has been described in a scarce number of patients. CLINICAL CASE: A 15-year-old previously healthy male patient with respiratory disease before his neurological deterioration presented to the emergency room after developing a complete medullary syndrome located at the cervical-dorsal level, with ascending and symmetric paraparesis that rapidly progressed to paraplegia, with sensory dysfunction from the T3 level, sphincter dysfunction and sudden ventilatory deterioration that required mechanical ventilation. Magnetic resonance imaging was compatible with acute TM. Inflammatory and non-inflammatory etiologies were discarded. In addition, a positive severe acute respiratory syndrome coronavirus 2 test was obtained. Treatment included steroid pulses and plasmapheresis, with an insidious evolution. CONCLUSION: COVID-19 is an infrequent cause of TM and should be suspected when other etiologies have been ruled out.
INTRODUCCIÓN: La mielitis transversa (MT) es una enfermedad inflamatoria desmielinizante que se presenta con disfunción motora, sensitiva y autonómica, de forma aguda o subaguda. La MT asociada al COVID-19 se ha escrito en un escaso número de pacientes. CASO CLÍNICO: Se presenta el caso de un masculino de 15 años previamente sano, quien cursaba con un cuadro respiratorio y que desarrollo un deterioro neurológico súbito que involucro un síndrome medular completo localizado en el nivel cérvico dorsal, con paraparesia simétrica que progreso a la paraplejia, con disfunción sensitiva desde el nivel medular de T3, disfunción de esfínteres y deterioro ventilatorio que requirió manejo avanzado de la vía aérea. Su resonancia magnética fue compatible con mielitis transversa aguda. Se descartaron causas inflamatorias y no inflamatorias de la patología. Además, se obtuvo un resultado positivo de SARS-COV-2. Se inició tratamiento con pulsos de metilprednisolona y plasmaféresis, con una evolución insidiosa. CONCLUSIÓN: El COVID-19 es una causa infrecuente de MT y debe sospecharse cuando otras causas han sido descartadas.

ABSTRACT: Paraparesis following cardiac surgery is a manifestation of spinal cord injury (SCI). It can occur in any aortic surgery from the aneurysm to the coarctation of the aorta (CoA) where the cross-clamp of the aorta is applied. Though the incidence of paraplegia is low, its occurrence affects the morbidity and mortality of the patient. There are only sporadic case reports on the development of paraplegia following recurrent and technically challenging repair of CoA. However, the spontaneous development of paraplegia has also been reported in cases of unoperated CoA. The present report describes the case of delayed SCI in which paraparesis developed 5 days post a coarctation repair. The risk factors and strategies to protect the spinal cord during aortic surgeries are emphasized.

INTRODUCTION: This case report documents a postoperative, incomplete sensorimotor paraparesis from thoracic vertebral body 6 (Th6) after combined anesthesia for upper abdominal surgery in a patient who had a thoracic localization of spinal epidural lipomatosis (SEL). CASE PRESENTATION: The patient was treated in our clinic with a thoracic epidural catheter (TEA) for perioperative analgesia during a partial duodenopancreatectomy. Paraparetic symptoms occurred 20 hours after surgery. Initial MRI did not show bleeding, infection or spinal cord damage and the neurosurgeon consultants recommended observation. The neurological examination and the third follow-up MRI on 15th postoperative day showed ventrolateral damage of the spinal cord at level Th6. It is possible that local anesthetic compressed the spinal cord in addition to the existing lipomatosis and the thoracic kyphosis. The paraparesis improved during follow-up paraplegiologic treatment. CONCLUSION: So far, only two uncomplicated lumbar epidural catheter anesthesias have been described in patients who had a lumbar SEL. Epidural catheter anesthesia is a safe and effective method of pain control. But it is important to carefully identify and stratify patients with risk factors during the premedication visit. In patients who had kyphosis and thoracic localization of SEL, TEA may only be used after a risk-benefit assessment.

OBJECTIVE: Spinal cord ischemia (SCI) with paraplegia or paraparesis is a devastating complication of complex aortic repair (CAR). Treatment includes cerebrospinal fluid drainage, maintenance of hemoglobin concentration (>10 g/L), and elevating mean arterial blood pressure. Animal and human case series have reported improvements in SCI outcomes with hyperbaric oxygen therapy (HBOT). We reviewed our center's experience with HBOT as a rescue treatment for spinal cord ischemia post-CAR in addition to standard treatment. METHODS: A retrospective review of the University Health Network's Hyperbaric Medicine Unit treatment database identified HBOT sessions for patients with SCI post-CAR between January 2013 and June 2021. Mean estimates of overall motor function scores were determined for postoperative, pre-HBOT, post-HBOT (within 4 hours of the final HBOT session), and at the final assessment (last available in-hospital evaluation) using a linear mixed model. A subgroup analysis compared the mean estimates of overall motor function scores between improvement and non-improvement groups at given timepoints. Improvement of motor function was defined as either a ≥2 point increase in overall muscle function score in patients with paraparesis or an upward change in motor deficit categorization (para/monoplegia, paraparesis, and no deficit). Subgroup analysis was performed by stratifying by improvement or non-improvement of motor function from pre-HBOT to final evaluation. RESULTS: Thirty patients were treated for SCI. Pre-HBOT, the motor deficit categorization was 10 paraplegia, three monoplegia, 16 paraparesis, and one unable to assess. At the final assessment, 14 patients demonstrated variable degrees of motor function improvement; eight patients demonstrated full motor function recovery. Seven of the 10 patients with paraplegia remained paraplegic despite HBOT. The estimated mean of overall muscle function score for pre-HBOT was 16.6 ± 2.9 (95% confidence interval [CI], 10.9-22.3) and for final assessment was 23.4 ± 2.9 (95% CI, 17.7-29.1). The estimated mean difference between pre-HBOT and final assessment overall muscle function score was 6.7 ± 3.1 (95% CI, 0.6-16.1). The estimated mean difference of the overall muscle function score between pre-HBOT and final assessment for the improved group was 16.6 ± 3.5 (95% CI, 7.5-25.7) vs -4.9 ± 4.2 (95% CI, -16.0 to 6.2) for the non-improved group. CONCLUSIONS: HBOT, in addition to standard treatment, may potentially improve recovery in spinal cord function following SCI post-CAR. However, the potential benefits of HBOT are not equally distributed among subgroups.

OBJECTIVE: Paraplegia is one of the most feared complications after thoracoabdominal aortic aneurysm repair. The purpose of this study is to determine whether aortic thrombus characteristics are associated with spinal cord ischemia (SCI) after branched endovascular aneurysm repair (BEVAR). METHODS: From April 2011 to April 2020, 62 patients underwent elective BEVAR for thoracoabdominal aortic aneurysm and pararenal aortic aneurysms using a low-profile device and had a complete preoperative computed tomography angiography of the aorta from the sinotubular junction to the aortic bifurcation. Aortic thrombus was evaluated for thrombus thickness ≥5 mm, thrombus >2/3 of aortic circumference, and the presence of an ulcer-like thrombus. One point was assigned at each 5 mm axial image if all 3 criteria were met, resulting in a total "shaggy score" for the entire aorta. Data on demographics, procedural details, and outcomes were collected prospectively. All patients underwent a standard spinal cord protection protocol, including routine cerebrospinal fluid drainage. In July 2016, an insulin infusion protocol (IIP) was initiated to maintain postoperative blood glucose levels <120 mg/dL for 48 hours. The primary clinical end point was postoperative SCI. RESULTS: 10 (16%) patients developed postoperative SCI: 6 with transient paraparesis, 2 with persistent paraparesis, and 2 with persistent paraplegia. Patients with SCI were older, had higher shaggy scores, and were less likely to have been on an IIP. There were no significant differences in demographics, aneurysm type, or operative parameters. In a logistic multivariate regression model for SCI, age (odds ratio [OR]: 1.2 [1.1-1.4], P = .02) and shaggy score (OR: 1.2 [1.1-1.4], P = .02) were independently associated with increased risk of SCI, whereas treatment with the IIP was associated with lower risk of SCI (OR: 0.04 [0.006-0.50], P = .05). Of the individual components of the shaggy score, higher descending thoracic aortic ulcer scores were the most strongly associated with postoperative SCI (P = .009). CONCLUSIONS: Preoperative characterization of aortic wall thrombus is an important adjunctive tool for individualized clinical decision-making and patient counseling about the risk of SCI after BEVAR.

STUDY DESIGN: Retrospective multicenter study. OBJECTIVES: Although surgery is frequently selected for the treatment of idiopathic spinal cord herniation (ISCH), its impact on functional outcomes has yet to be fully understood given the limited number of patients in previous studies. This study aims to evaluate the symptomatic history and surgical outcomes of ISCH. SETTING: Three institutions in Japan. METHODS: A total of 34 subjects with ISCH were retrospectively enrolled and followed up for at least 2 years. Demographic information, imaging findings, and clinical outcomes were collected. Functional status was assessed using the JOA score. RESULTS: The types of neurologic deficit were monoparesis, Brown-Sequard, and paraparesis in 5, 17, and 12 cases, with their mean disease duration being 1.2, 4.2, and 5.8 years, respectively. Significant differences in disease duration were observed between the monoparesis and Brown-Sequard groups (p < 0.01) and between the monoparesis and paraparesis groups (p = 0.04). Surgery promoted significantly better recovery rates from baseline. Correlations were observed between age at surgery and recovery rate (p < 0.01) and between disease duration and recovery rate (p = 0.04). The mean recovery rates were 82.6%, 51.6%, and 29.1% in the monoparesis, Brown-Sequard, and paraparesis groups, respectively. The monoparesis group had a significantly higher recovery rate than did the Brown-Sequard (p = 0.045) and paraparesis groups (p < 0.01). CONCLUSIONS: Longer disease duration was correlated with the progression of neurologic deficit. Older age, and worse preoperative neurologic status hindered postoperative functional recovery. These results highlight the need to consider surgical timing before neurologic symptoms deteriorate.

Spinal dural arteriovenous fistula (SDAVF) is also known as a type 1 spinal arteriovenous malformation, representing the most frequent vascular malformation of the spine. A high suspicion index is often required for the initial diagnosis of SDAVF because of subtle magnetic resonance imaging signs. We present the case of a patient with SDAVF associated with syringomyelia of the thoracic spinal cord and hypothesize that a fistula might induce intramedullary fluid accumulation due to venous hypertension, which leads to syrinx formation.

Patients with acute to subacute multifocal neurologic abnormalities often have a unique presentation, and their diagnosis and management can be challenging. We present the case of a 40-year-old patient who presented with a 4-day history of confusion, bradyphrenia, right facial droop, bilateral lower limb weakness, urinary incontinence, and hypothermia. This case highlights the diagnostic approach to patients with subacute multifocal neurologic abnormalities, the importance of considering coexisting systemic illnesses in the diagnosis, and their management. Readers will explore the diagnostic steps our group has considered to reach our final diagnosis and the importance of management for our leading diagnosis.

A 1-year-old, female English Bulldog presented with a 10-day history of progressive paraparesis. Neuroanatomical localization was consistent with T3-L3 segment myelopathy. Magnetic resonance imaging (MRI) revealed a severely compressive, mildly contrast enhancing, extradural, dorsal, broad-based mass at the level of L3-4. Similar, non-compressive, smaller nodules were present along the extradural space and dura mater of the caudal lumbar spine. Owners elected euthanasia based on these imaging findings and progressive clinical signs. Necropsy, histopathology and immunohistochemistry revealed a mesenchymal mass and nodules, admixed with numerous inflammatory cells. The diagnosis of an extradural inflammatory myofibroblastic tumor (IMT) with a multifocal presentation was made.

Intramedullary tuberculoma (IMT) is considered to be a rare form of spinal tuberculosis (TB). Overall, TB of the central nervous system accounts for approximately 1% of all cases of TB and 50% of these involve the spine. The clinical presentation of spinal intramedullary TB is similar to an intramedullary spinal cord tumor mass. The factors attributable could be malnutrition, poor socioeconomic conditions, and immunodeficiency syndromes. As per the reports, the incidence of primary intramedullary TB is 2 in 100,000 cases among patients with TB. We describe one such patient who presented with progressive asymmetrical paraparesis due to histologically confirmed intraspinal tuberculoma. Paraparesis in spinal IMT is considered to be rare. Hereby, we present the case of a 29-year-old female who presented with asymmetric onset paraparesis of 6 months with associated numbness and tingling began in the left foot 3 months which was ascending in nature. There was no history of stiffness, involuntary movements, flexor spasms, thinning, or fasciculations of muscles. There was a loss of sensation pain, touch, and temperature below L3 with normal reflexes. Power in both the lower limbs was 1/5 as per Medical Research Council (MRC) grading. She underwent a contrast magnetic resonance imaging spine which was suggestive of an intramedullary SOL at D12 vertebral level. The patient underwent surgical intervention with resection of the SOL. Histopathology was confirmed to be an IMT. She was started on Category 1 (antitubercular drugs) and further investigated for primary source, which was found to be negative. We want to emphasize that TB can involve any part of the body. It should be kept as a differential diagnosis of any chronic inflammatory lesion involving the bony skeleton, especially in endemic countries where combined surgical and medical treatment is usually sufficient to provide a cure.

Vertebral haemangioma is a benign vascular tumour mostly seen in the thoracic region of the spine. Spinal haemangiomas are usually asymptomatic and are discovered incidentally. In a few patients, however, aggressive vertebral haemangiomas can cause local pain, radicular pain or neurologic deficits, which result from neural compression. The aetiology of the origin is unclear and is probably multifactorial. Hormonal and biological changes in pregnant women can lead to accelerated vascular growth of haemangioma. In our report, we present the case of a pregnant patient who was diagnosed with an aggressive vertebral haemangioma that further led to progressive paraparesis. We had to take the fact that she was pregnant into account in the diagnostic procedure, in the choice of examination method and also in the method of therapy. The goal of this case report is threefold: (1) provide an overview of the possible methods of management, specifically imaging, which will aid in diagnosis and based on that, (2) determining the appropriate therapy and (3) review the risks and benefits of each will be presented when choosing individual approaches.
